Answer:
40 square units
Step-by-step explanation:
First of all, lets say that square has side 
, so, the area unit is 
the diagonal's square is 
CALCULATION OF TRIANGLES'S AREA (there are 4 triangles)
CALCULATION OF MAIN SQUARE AREA
TOTAL AREA
Complete question :
Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.
Answer:
1.625 yards
Step-by-step explanation:
Purple ribbon = 7/8 yards
Green ribbon = 1 1/6 yards = 7/6 yards
Total ribbon = 3 2/3 yards = 11/3 yards
Ribbon that is neither purple nor green :
Total ribbon - (green + purple ribbon)
7/8 - (7/6 + 7/8)
11/3 - (28 + 21) / 24
11/3 - 49/24
= 1.625 yards
Answer:
Step-by-step explanation:
The bottom leg is divided into equal segments, one of them is b.
It means the bottom leg is b + b = 2b.
<u>According to Pythagorean:</u>
<u>Solve for b:</u>
- 1681 = 4b² + 81
- 4b² = 1681 - 81
- 4b² = 1600
- b² = 400
- b = √400
- b = 20 cm
All functions have a dependent variable. TRUE
All functions have an independent variable. TRUE
The range of a function includes its domain. FALSE
[Range refers to the set of outputs the function produces, domain the set of inputs the function accepts. They don't really have to have anything to do with each other.]
A vertical line is an example of a functional relationship. FALSE
[For a function, each input (x value) maps to at most one output (y value). A vertical line has lots of ys for a single x.]
A horizontal line is an example of a functional relationship. TRUE
[It's a constant function.]
Each output value of a function can correspond to only one input value. FALSE
[A function can have the same output given different inputs, for example f(x)=x^2 has f(1)=f(-1) ]
